#1 0x00007f31b9705524 in __GI_abort () at abort.c:79

[**ALERT: The abort() might not be exactly invoked from the following function line.
If the trail function contains multiple abort() calls, then you should cross check by other means to get correct abort() call location.
This is due to the optimized compilation which hides the debug info for multiple abort() calls in a given function.
Refer TR HU16995 for more information]
